I attached one simple application to this post. Do you believe that I develpoed it in a day? The Idea, the colors, everything. Awesome! Evaluate It. Its just a simple program (that's why its free) but its still useful. You can use it to calculate the determinant of a 3 by 3 square maltrix. Its very easy. Just type the values in each cell and click calculate. It comes with source code so that young programmers on this forum can learn from it. I wrote it because of them. Remember that you need to hava JDK on your PC to run it. You are free to modify the source code. You can also add it to your website but don't forget that I wrote the program. Please evaluate this program. You can send your comments to marvelindaclub@yahoo.comI can help you develop your huge projects at an afoordable price. |

Nice work you done here.but there were one or two i noticed which i thought i should bring to your attention.
All of your textboxes had default text in them and i was kind of surprised these texts were not cleared when the textbox in question received focus.thus i had to delete the default text before entering my test values.This is not at all user friendly.
Solution 1: There is an event listener class, "FocusListener" in package java.awt which you could have used.It declares 2 methods: "public void focusGained" and "public void focusLost". you'll just implement the focusGained method to set the text of the event source to an empty string like this:
public void focusGained(FocusEvent event){
event.getSource().setText() == "";
}
then register it to the textbox - your JTextField like this myBox.addFocusListener(FocusListener f).Better still you could use a focusAdapter class and just override the "foucsGained" method.
And please be gentle with the colours.
Once again. Nice work.

Shimao thank you for your observation. I have already considered the colors and I have updated the application. The update has an appearance panel with threee radio buttons, "Old School", "Bold 'n' Colourful" & "Sayo". The Old School radio button takes away all the colours. While the sayo radio button sets the whole colors to one single color(blue). The update is actually a show-off of Look and Feel, MouseMotionListener (for highlighting buttons when the pointer is on them), Boardered Panel with title string e.t.c. I first accessed your reply on mobile phone so it was not so clear, so I have to browse on a PC. Now every thing is perfectly clear to me. I shall update it tomorrow and paste it here. When I saw you point concerning the default text, the first thing that came to my mind was to use MouseMotionListener so that the text automatically disappears when the pointer is on the text fields. So thank you for calling my attention to use focus because it would have been a long code, you know? But that focus is just a few lines. Once again thank you.

I need someone to teach me how to by-pass that security frame and access the main program, assuming the source code and the class files are not supplied with the program. I know that security is a weak one but like what kind of people are capable of breaking such. please teach me if you can.
